Add dry ingredients to mug, and mix well. Add the egg and mix thoroughly. Pour in the milk and oil and mix well. Add the vanilla extract, and mix again.

Put your mug in the microwave and cook for 3 minutes at 1000 watts (high). The cake will rise over the top of the mug, but don't be alarmed! Allow to cool a little, and tip out onto a plate if desired. Enjoy!

Haha, thanks for the amusing comments! Anon, I'd try to cook it a little less, since your microwave might be more powerful than mine (got mine in a raffle in 2004--yep. You just turn the crank for the time/temp you want. No buttons or anything). You might also want to let it cool a bit. Then it goes from fudgy to slightly spongy and cakelike.

I love this recipe. I have made it 3 times, all while drunk and twice it turned out great. The not-so-great time happened when I substituted hot cocoa mix for the real cocoa. I could not get the hardened substance out of my Christmas mug and ended up having to through out the entire mug. NO SUBSTITUTIONS! Delish!

To really make this cake yummy (and many more calories) you can add to it! :) We made this tonight with friends (instead of studying). Here's how we changed up the recipie:

Took the yolk out of the egg (to cut down on the "eggy" flavor we experienced)

Added: Hershey's chocolate syrupCaramel ice cream toppingpeacanschocolate chipscoconut and 1 large marshmallow to the middle of the whole thing after it was all mixed together --- this is not advisable because the marshmallow got as large as a small tennis ball and wasn't a significant addition

While "stumblilng" tonight I found this recipe... even though it was 11:30pm I decided to try it. It's now 11:47 and I have this rubbery chunk of chocolate cake beside my computer. It is edible, and would cure an emergency chocolate craving but I wouldn't suggest serving it to company.

I discovered this a while ago after my mummy sent it to me..i guess we both have loving mothers X3 i've changed it a little by substituting oil with melted butter and changing a tbsp of sugar for cocoa. Also make sure if yoy have a high powered microwave to put it on a lower setting (about 1000 watts) or put it in fo less time. Its a little like pudding so delicious with ice cream!

My cousin and I just tried to make this, but unfortunately, it turned out dreadful. After we put it in the microwave, it started to smell really gross, and once we took it out, it didn't smell good, or taste good at all. It was all rubbery, with a horrible after taste.

Maybe we made it wrong? Who knows. I'm guessing so since all of the other comments say it works perfectly. I'll try it again sometime.

Pretty good! Only thing I changed was I put a pinch of salt and a handful of chocolate chips in... which of course sank to the bottom and left and nice little surprise for me. And it was a big helping! I could only eat about half of it. I quite liked the fudgy-ness of it. Props.

homfg this is so evil. but amazing. The cake turned out pretty dang good considering i made it so fast. Texture wasn't perfect but still tasted like chocolate cake. 8D I plan on experimenting with this a lot in the future. *0*

So I played around with this recipe a bit. I replaced the oil with butter and whipped the egg. I cooked it for 2 minutes and 30 seconds instead of 3 minutes. And I topped it with cream as another person suggested. I like the results a lot. C: Came out with a better texture. Less spongy. But quite different from the original result. Om nom nom.

i have added a link of you recipe to my facebook group 'mug + microwave + awesome' thankyou you so much for this recipe i tryed it 2 mins after i read it and it was great. few things i would change but keep these recipes comingthankyou if u have any problems with this please contact me thur this group thankyou for hte insparation to start it

Loved this recipe for a long time and just had it again recently and it was the best one yet. *o*

I replaced the oil with butter and whipped the egg beforehand. I cooked it for 2:30 instead as well to insure it didn't get spongy. Topped it off with whipped cream that seeped wonderfully into the cake making it very moist. So good. Thinking about adding some chocolate chips next time too.

I think the most important thing to remember here is to not cook it too long. Try cooking at 2 minutes or 2:30 at first just to be sure.
